When Giza Pyramid builders laid the first layer of limestone blocks for the Great Pyramid, all that was required for the second layer was a method of leverage using the first layer, and so on for progressive layers. Just as human-beings walk upward on steps, step by step, Giza engineers raised Pyramid blocks step by step, thereby using all space available over the entire Pyramid’s four sides progressively until completion.
Tomb models of “Petrie rockers” provide evidence of the “four-lobe pinion-pulley” which surround a Pyramid block and step walks its load when hoisted. The Giza Pyramid builders used the earliest known example of “Rack and Pinion” engineering technology, where the Pyramid consists of four sides of limestone Racks and the Four-Lobe pulleys are the Wooden pinions interacting the racks with positive displacement.
